Vacuum Advance

[klwebb]

A family friend told my dad that the reason my truck bogs down when you hit the gas too hard is the vacuum advance? i can slowly accelerate and it does fine, but my dad wants me to be able to get out into traffic quickly so i dont cause a wreck. can someone explain what a vac advance is/how it works (and where it is) and how i can adjust it? i have a 350 with a 4barrel rochester carb

or does anyone have any other ideas why it bogs down like this? yeah its a slow truck, but it shouldnt die when i want to get up and go
